项目导入第三方包的时候出现
Execution failed for task':app:transformResourcesWithMergeJavaResForDebug More than one file was found with OS independent path"META-INF/rxjava.properties'的错误，如下图所示：
查看Gradle Console打印的日志为：
解决方案是：
在app下的build.gradle的配置文件的android闭包中添加如下：
packagingOptions {
//解决编译时com.android.builder.merge.DuplicateRelativeFileException: More than one file was found with OS independent path 'META-INF/rxjava.properties'这个错误
exclude 'META-INF/rxjava.properties'
}
点击Sync Now同步一下重新编译OK。
